Uvex S1933X Skyper Safety Visor with Black Frame and SCT-Orange UV Protection and Extreme Anti-Fog Lens

Pros- Came a few days earlier than promised. Good for continuous screen users. Slept like a log of wood. Cons- came in a box almost crushed cost can be lower Please provide a case(if needed charge)-For heavens sake packing it in a plastic paper was !!!!!!!!

My sleeping problem, eyes swelling & going red stopped after using the glasses though I look into computer screen for more than 12 hours a day.

Does work as advertised. It gets scratched a bit easily though. On cleaning, lint does stick to it's surface. Other than that is comfortable for long wear and adjustable enough to fit any sized face.

Received the product well before the estimated delivery schedule.. Was useful.

Very easily it gets scratches. Poor glass quality. Good thing about the product is that it covers your eyes totally and there is no strain on the eyes.

Truly blocks blue light; reduces eye strain by 90%; worth it for those who need to use computers constantly

Price is high when compared to the quality of the product. Don't think it provide better and safe vision for watching laptops, TV or mobile.

Bought one after listing to dr.jack kruse and also reading some research on how Blue light permanently kills off our photo receptors.. i have to say it absolutely makes a difference.. this one truly blocks bluelight.. first i got a bluelight filter glasses from Amazon.in .. For 650rs... Thought they did helped a lil to reduce straight but i didn't felt satisfied.. then I ordered this from nv craze seller and got it in Whitn 9-10 days.. amazing..i was so happy.. it literally makes most like 98% bluelight filter..u will barely be able to see blue light coming from electronics as blue .blue colors turns either black or grey and yess it will help your sleep, eye strain and vision clarity.. looking through these lenses is surprisingly clearer then expected.. like everything lights up.. In oragnish tint. Also these are the same uvex glasses used in research to prove that amber tinted glasses really block bluelight

Realmente funcionan y bloquean el espectro nocivo de luz azul. Los armazones son de plástico pero lo suficientemente rígidos y cómodos para darle una buena vida útil a los lentes. Las micas se pueden intercambiar, ya que se desprenden del armazón. La gente que se queja de que se rayan, es porque no los limpia con paño antiestático o si lo hace, los fricciona en exceso. No son incómodos y no pesan. Se acostumbra uno al instante. Si los vas a usar para ver la TV o jugar algún videojuego, debo advertirte que los matices de los colores si se verán distintos. Principalmente todos los azules (dependiendo de la longitud de onda a la que pertenezcan se verán negros y/o verdes) y los blancos se verán naranjas. Aunque claro, es preferible proteger los ojos en este caso, porque si estás buscando lentes bloqueadores es porque definitivamente tienes algún problema u afección en tus ojos. Los lentes también ayudan a descansar la vista cuando se está mucho tiempo frente a un monitor, puesto que la luz nociva no penetra, generando un descanso visual y una mayor eficiencia de nuestro ritmo circadiano. Recomiendo estos lentes ampliamente.

As an amateur astronomer, I've done a lot of research about light pollution. That led me to research about how light affects sleep. Here's the summed-up version so you don't need to read all those scientific papers I have: - Blue light is great for being awake - that's why you wake up with a blue sky (read about melanopsin and melatonin on Wikipedia) - Blue light is not good for sleep; in the 470 nanometers range, that suppresses melatonin (a key hormone for sleeping well) - Humans (and other animals) evolved to sleep in the dark - or, at the darkest, full Moonlight (just 0.1-0.3 lux of light) - Longer wavelengths of light were the only source of light at night for most of human history (fire / candles) - Tablets / phones / screens / LED's and many CFL bulbs have strong blue wavelengths that are messing with our circadian rhythms and suppressing melatonin, because they have wavelengths shorter than 530nm - 540nm So what to do in our modern world? Wear these glasses before bed. Natural melatonin production would have occurred with our ancestors starting with the onset of sunset. Wavelengths of light from the setting sun would have shifted to red, and fire or candles were usually the only form of light available. Those are both relatively dim, and in longer wavelengths. Today, our "connected" world has a LOT of blue light. It's messing with our sleep patterns, because our bodies evolved to only see red/orange/yellow light at night, NOT blue light/shorter wavelenghts. THESE GLASSES BLOCK THOSE MELATONIN SUPPRESSING WAVELENGTHS. Put them on a couple hours before bed. For me, I start getting drowsy about 90 minutes after wearing them. The trick is DO NOT take them off without closing your eyes or being in a dark room (a room with ONLY a dim red light would work too, as your melanopsin won't trigger melatonin suppression with red light). So when changing for bed, close your eyes when removing your shirt if you have to pull it off over your head or put your night time clothing on. Then leave these on until you turn out the light for sleep. And be sure to sleep in the dark too, or wear a sleep mask. Small amounts of light can still affect your melatonin (well, anything brighter then full Moonlight - yes, even a blue LED on your computer). You can watch TV with these on, check your phone, read your tablet, work on your laptop - just note that colors will look weird. Blue looks black. Yellow looks white. Greens look weird. And the glasses aren't exactly stylish. But if you sleep better, who cares? They work. And while you're at it, make sure your home's lights (and business if you own one) aren't shining into other people's homes or apartments. Too much light at night is what makes these things necessary in the first place. We don't need all this light at night; these glasses are just a band aid to help; what we really need is smarter outdoor lighting - aimed down, at the ground, at the proper color(s) so we aren't suppressing others melatonin. According to a Harvard study, the U.S. loses $63 BILLION dollars per year due to American's insomnia. Artificial light at night messing up people's sleep is undoubtedly part of that - let's fix that so these glasses aren't as necessary. Oh, and did these glasses work for me? An emphatic YES, they did. 5 nights (so far) of excellent sleep and well-rested mornings. And I am NOT a morning person! They work - just use them the right way, and be sure you're not doing other things that might hurt sleep (too much caffeine, lack of / too much exercise right before bed, sleep apnea, etc.) So if it's not a medical condition, do the right things, wear these, and get better sleep.

I ordered a pair for my mom as she likes to look at her iPad in the evening for a couple hours to do her research and she loved them so much so I bought a pair of myself and they have been very helpful. They are only for home use, if they were for being at work I would want clear ones, but these actually have more protection being the amber color. I’m really happy with them.. I also love how they wrap around the side a little bit.

These are great quality for what you're paying. Use them with a light warming application such as f.lux for the best results. Positives: + They hug your face really well, the side shields keep light out and the tint makes sure no (or very little) blue light will reach your eyes. + I saw an analytical graphic and these glasses block out about 98% of blue light, more than enough to see the health benefits (better sleep etc). + A very good price point, well priced indeed. Negatives: - They aren't that stylish, but don't look awful either. They are substance over style, and do the job better than other products in this market that are geared more towards aesthetics. - Lower quality materials; this doesn't affect function at all; but plastic is always going to be worse than metal and more prone to breakage. - The strong tint may makes these unsuitable for situations where accurate color perception is necessary, for example playing video games. It's a trade-off, block out more blue light while forfeiting colours or block less blue light and seeing a broader colour spectrum - different glasses in this market will suit different needs.
